Newegg via eBay offers the iRobot Braava 320 Floor Mopping Robot for $119.99 with free shipping. That's tied with our mention from a week ago as the lowest total price we've seen. (It's a current price low by $19.) This robot mop uses the NorthStar Navigation System to map an efficient cleaning route and runs for up to three hours per charge. Deal ends March 6.
